SYSTEM FOR COLLECTING WATER.

Application led February 17, 1920.

To all whom t may concern Be it known that I, Davis P. HOWELL, a citizenof the United States of America, and resident of Modesto, in the countyof Stanislaus and State of California, have invented certain new anduseful Improvements in Systems for Collecting lVater, of which thefollowing is a specification.

This invention relates to well production and particularly to means forincreasing the capacity of wells and for increasing the supply of watercompared with that which would ordinarily collect at the bottom of awell where casings or well linings are employed in the hole.

A still further object of this invention is to provide a device of thischaracter which will not interfere with the pumping operation and inwhich the means for collecting the water or fluid at the bottom of theshaft or well is supplemental to that of the pump.

With the foregoing and other objects in view, the invention consists inthe details and in the arrangement of the collecting device withrelation to the pump shaft, and in describing the invention in detail,reference will be had to the accompanying drawing in which I haveillustrated by sectional view, the apparatus and method employed forcarrying the invention into practice.

- In these drawings I have shown conventionally, the formation throughwhich the well shaft or casing extends as having alternate layers 5 ofrelatively hard strata with interposed layers G of water bearing sand orother light disintegrated material, and 7 denotes the well shaft or holehaving a casing or lining 8 and this casing is supposed to be suppliedwith a water elevating mechanism of any appropriate type. As, however,the mechanism for raising or pumping the water has nothing to do withthe present invention, it will not be described in detail. Injuxtaposition to the first mentioned shaft or boring, another `shaft orhole 9 is Specification of Letters Patent.

produced having a casing l0 therein, and obviously, it is desirable thatthe second mentioned shaft shall be equal in depth to that of the rstmentioned so that any deposits of water in the second mentioned shaftmay reach the pool, water course or cavity from which the firstmentioned shaft is supplied.

In order to collect as much as possible of the water which may becontained in the strata through which the second mentioned shaft issunlr, the depth of each water bearing stratum from the surface isdetermined during the drilling operation, and at each said stratum, thecasing l0 is provided with one or more perforations in order that thewater may escape from the higher levels and 'descend through the casingto the bottom of the shaft 9 where it will find its way to the shaft 7to augment the body of water which may be pumped through the shaft 7.

I do not wish to be limited with respect to the location of theperforations with relation to any certain stratum nor to the type ofcasing employed, as the invention has to do more particularly with thesimple and comparatively inexpensive means for causing the water of thehigher levels to descend to the point where it can be removed in themanner stated.

lVhile I have referred to the well as being designed for the purpose ofcollecting` and pumping water, it is to be understood that the sameprinciple can be employed in connection with the recovery of oil andlike deposits.

I claim:

In a system for collecting water, a well through which the water israised, and a well shaft adjacent thereto extending to the level of thefirst mentioned well, a casing in the second mentioned shaft havingopenings at different levels where water bearing strata occur.
